It is those individuals who believe themselves to be leaders but are too lazy to acquire the knowledge required to effectively lead. Who remain in the background in times of adversity and struggle, shielding themselves at the expense of those around them instead pointing fingers at others. Those who look to take all the credit for success but deflect responsibility for failure are not leaders but rather cowards. Their actions inspire nothing more than contempt from those they are tasked with leading and their tenure is ultimately doomed to fail.
Great leaders understand as spider man once said with great power comes great responsibility. They stand by their people. They do not look to point fingers as a way of absolving themselves but understand that as the leader they must be willing to stand up and accept the criticism for each failure. They immerse themselves in the job understanding in all things knowledge is essential because without it their leadership is simply an illusion based on nothing more than bravado and arrogance.
The time for these individuals is usually short and once their time has passed and their chance to stand up and be a leader is forever lost history will record that their tenure to be nothing but a delusion of grandeur extinguished by a power far greater than they had hoped to ascend to, the power of the masses. Leaving them with nothing but time to wonder how they could have been a leader rather than coward.
